We’re looking for a mid level iOS engineer to join our small, experienced team. We want someone who is product-oriented and cares about how people will use and interact with the software they're building.

You will play a crucial role in shaping the future of mobile at Yoto, with ample opportunities to influence our direction and growth. We are looking for engineers who prioritise quality while thriving in a fast-paced environment.

Yoto is a screen‑free interactive audio platform for kids. We make carefully connected audio players that kids control, with no microphones, cameras or ads. We have a catalogue of audio that inspires creative play and learning with 1,000+ titles in our card store from top creators, publishers and labels – think Disney, Marvel, Roald Dahl and Universal Music. We also create Yoto Originals like Brain Bots.

Our codebase is entirely in Swift, with most of our UI now built in Swift

We use a range of established third‑party tools and services where appropriate, and are intentional about evolving the codebase as the product and team continue to grow.

Our user base is expanding rapidly, and we aim to grow the team sustainably to scale our codebase and support new features while refining existing work. We are particularly committed to improving performance and stability, as evidenced by our excellent crash‑free rate and App Store reviews.
